DETAILED DESCRIPTION

The detailed description of various embodiments herein makes reference to the accompanying drawings, which show various embodiments by way of illustration. While these various embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, it should be understood that other embodiments may be realized and that logical, chemical, electrical, and mechanical changes may be made without departing from the spirit and scope of the disclosure. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation.

For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, connected, or the like may include permanent, removable, temporary, partial, full, and/or any other possible attachment option. Additionally, any reference to without contact (or similar phrases) may also include reduced contact or minimal contact.

For example, in the context of the present disclosure, methods, systems, and articles may find particular use in connection with autonomous aircraft cargo handling systems. However, various aspects of the disclosed embodiments may be adapted for performance in a variety of other systems such as ground cargo handling systems. As such, numerous applications of the present disclosure may be realized.

As used herein, “aft” refers to the direction associated with the tail of an aircraft, or generally, to the direction of exhaust of the gas turbine. As used herein, “forward” refers to the direction associated with the nose of an aircraft, or generally, to the direction of flight or motion.

Aircraft cargo handling systems as disclosed herein may allow autonomous loading and/or unloading of cargo units from an aircraft. In that regard, aircraft cargo handling systems as disclosed herein may result in increased efficiency of loading and unloading processes and reduce human operator involvement and the human error and safety risks involved therewith.

In various embodiments, and with reference to FIG. 1, a schematic view of an aircraft 10 having a cargo deck 12 is illustrated. Aircraft 10 may comprise a cargo load door 14, for example, at a side of the fuselage structure of aircraft 10, at an aft end of the fuselage structure, and/or at any other suitable location. Cargo unit 20 may be loaded through cargo load door 14 and onto cargo deck 12 of aircraft 10 or unloaded from cargo deck 12 of aircraft 10. Although cargo unit 20 is illustrated as a cargo container, cargo unit 20 could also be a pallet, an irregularly shaped object, an irregularly shaped container, or other cargo.

Items to be shipped by air, freight, and/or the like are typically loaded first onto specially configured pallets or into specially configured containers, also known as unit load devices or “ULDs.” In that regard, as referred to herein, “cargo unit” may also refer to a ULD. ULDs are available in various sizes and capacities, and are typically standardized in dimension and shape. Once loaded with cargo items, the ULD is transferred to aircraft 10, and is loaded onto aircraft 10 through cargo load door 14 using a conveyor ramp, scissor lift, or the like. Once inside aircraft 10, the ULD is moved within cargo deck 12 to its final stowage location, as discussed further herein. Multiple ULDs may be brought on-board aircraft 10, during one or more loading procedures (e.g., at separate destinations), with each ULD being placed in its respective stowage and transportation location in cargo deck 12. After aircraft 10 has reached its destination, one or more ULDs may be unloaded from aircraft 10 similarly, but in reverse sequence to the loading procedure.

In various embodiments, and with reference to FIG. 2, a top view of an end-to-end cargo loading operation 100 illustrated from a top view, in accordance with various embodiments. Aircraft 10 may comprise a cargo deck 12 configured to receive and store one or more cargo units 20 for a flight. As referred to herein, cargo deck 12 may comprise an “active” cargo deck comprising a plurality of electromechanical actuators embedded in cargo deck 12 or a “passive” cargo deck devoid of a plurality of electromechanical actuators embedded in cargo deck 12. Cargo deck 12 may comprise a plurality of rolling elements on a surface of cargo deck 22 configured to assist in movement of cargo unit 20 over cargo deck 12. Cargo deck 12 may extend aftward (in the positive Z-direction) toward a rear portion of aircraft 10 and be positioned adjacent to cargo load door 14. However, there are many other aircraft cargo deck configurations to which the embodiments of the disclosure can be implemented. For example, various aircraft, particularly those designed primarily for the transportation of cargo without passengers, may have the upper passenger deck removed and an additional larger cargo deck installed. Cargo unit 20 may be transported to destination location 16, wherein cargo unit 20 may be secured for the duration of a flight. While illustrated as being positioned at an aft-most location on cargo deck 12, destination location 16 may be at any location on cargo deck 12 such as a forward location of cargo deck 12 or middle portion of cargo deck 12. Further, destination location 16 need not be directly on top of cargo deck 12 and may be on top of other cargo units already positioned directly on cargo deck 12. Destination location 16 may define one “end” of the end-to-end cargo loading operation 100.

In various embodiments, cargo load door 14 may be adjacent to a lift unit 30. Lift unit 30 may be configured to lift cargo unit 20 from a ground surface to an elevation equal or greater than that of cargo deck 12. Cargo unit 20 may then be loaded onto aircraft 10 through cargo load door 14. As discussed further herein, cargo unit 20 may be moved from lift unit 30 and moved along a plurality of roller elements on cargo deck 12 until cargo unit 20 arrives at destination location 16. Lift unit 30 may be positioned on a path 50 which may extend between aircraft 10 and warehouse 60. In various embodiments, more than one path 50 may be situated between aircraft 10 and warehouse 60.

Still referring to FIG. 2, in various embodiments one or more transportation units 40 may be configured to travel to and from aircraft 10 and warehouse 60. Transportation unit 40 may be configured to transport cargo unit 20 to lift unit 30, wherein lift unit 30 can then elevate cargo unit 20 such that it can be moved through cargo load door 14 and onto cargo deck 12. As discussed further herein, transportation unit 40 may be configured to travel from warehouse 60 along path 50 to aircraft 10 and then travel from aircraft 10 along path 50 to warehouse 60. Stated otherwise, transportation unit 40 may travel to and from aircraft 10 such that cargo transportation unit may assist in loading and unloading operations.

Transportation unit 40 may be configured to enter warehouse 60 and move about cargo loading area 62 wherein transportation unit 40 may be loaded with and/or load a cargo unit 20. For example, transportation unit 40 may be configured to travel to intermediate location 64, where transportation unit 40 may be loaded with cargo unit 20 with the assistance of a human operator manually maneuvering cargo unit 20 or moving cargo unit with a fork lift or the like. In various embodiments, transportation unit 40 may be configured to self-load cargo unit 20 through an electromechanical actuator on transportation unit 40. In various embodiments, such an actuator may be an electrically, hydraulically, or pneumatically powered clamp, lift, pulley system, or the like.

In various embodiments, cargo unit 20 may be positioned in intermediate location 64 by a human operator manually maneuvering cargo unit 20 or moving cargo unit with a fork lift or the like. Prior to being positioned in intermediate location 64, Cargo unit 20 may be positioned at initial location 84 on a freighter 80, which in various embodiments may be a freight truck, van, or the like. Cargo unit 20 may be moved from freighter 80 through a freighter loading door 82 and along path 70 to intermediate location 64 in warehouse 60. In various embodiments, cargo unit 20 may be positioned in intermediate location 64 via human operator or via transportation unit 40. Initial location 84 may define the other “end” of the end-to-end cargo loading operation 100. However, in various embodiments, intermediate location 64 may also define an “end” of the end-to-end cargo loading operation 100. Accordingly, as referred to herein, end-to-end cargo handling operations and/or systems may refer to movement of a cargo unit from a freighter to a warehouse to an aircraft, from a warehouse to an aircraft, or any other combination of movement between two locations.

In various embodiments, transportation unit 40 may be configured to move along path 50, throughout warehouse 60, and along path 70. In various other embodiments, transportation unit 40 may be configured to operate on path 50, in warehouse 60, or on path 70 or any combination thereof. In various embodiments, a separate transportation unit 40 may be positioned on each of path 50, warehouse 60, and path 70. Therefore, a single transportation unit 40 or a plurality of transportation units 40 may assist in moving cargo unit 20 between intermediate location 64 or initial location 84 and destination location 16.

Transportation unit 340 may receive positioning information of lift unit 330 via network 360 and may travel to that location to transfer cargo unit 320 to lift unit 330.

With reference to FIG. 3B, in various embodiments, cargo unit 320 may be transferred from transportation unit 340 to lift unit 330. Cargo unit 320 may be transferred from transportation unit 340 to lift unit 330 via human operator, human operated machinery such as a fork lift or the like, via actuators present on transportation unit 340 or on lift unit 330, or in any other suitable manner. Upon receiving cargo unit 320, lift unit 330 may be instructed via control module 350 to lift cargo unit 320 to a location near a cargo load door of aircraft 310. In various embodiments, lift unit 330 may comprise a scissor lift, fork lift, conveyer belt, overhead crane, or other suitable mechanism capable of raising and/or lowering cargo unit 320 to and/or from aircraft 310. In various embodiments, lift unit 330 may comprise a sensor configured to sense the presence of cargo unit 320, signaling the need to lift cargo unit 320. For example, in various embodiments, lift unit 330 may comprise a camera, a structured light sensor, a light detection and ranging (LiDAR) sensor, an infrared sensor, a depth sensor (e.g., an IR projector/camera assembly such as a MICROSOFT® Kinect®, an ASUS® Xtion PRO®, etc.), a 3D scanner/camera, an ultrasound range finder, a radar sensor, and/or any other suitable sensing device. The sensor may also comprise a sensor capable of sensing a weight of an object (a “weight sensor”) such as, for example, a pressure sensor, a piezo-electric sensor, and/or the like. During this time, transportation unit 340 may also be receiving instructions from control module 350 to travel elsewhere to complete other tasks such as retrieving another cargo unit waiting to be loaded on aircraft 310. Once cargo loading of aircraft 310 is complete, the aircraft cargo loading door may close via one or more sensor or through instructions provided by control module 350 over network 360 to aircraft transceiver 318.

Moving on and with reference to FIGS. 4A and 4B, autonomous end-to-end cargo handling system 400 is illustrated, in accordance with various embodiments. Autonomous end-to-end cargo handling system 400 may be similar to the autonomous end-to-end cargo handling system 300 of FIGS. 3A and 3B.

In various embodiments, autonomous end-to-end cargo handling system 400 may comprise an autonomous multifunction unit 480, which may be configured to assist in one or more tasks. For example, in various embodiments, multifunction unit 480 may be configured to travel between a first location and a second location, load one or more cargo units 420, relocate the one or more cargo units 420, and lift the one or more cargo units 420 to be loaded onto aircraft 410.

For example, in various embodiments, multifunction unit 480 may comprise a lift unit 430 comprising a lift unit transceiver 432 and a transportation unit 440 comprising a transportation unit transceiver 442. In various embodiments, both lift unit 30 and transportation unit 440 may be configured to move between a first location and second location. Lift unit 430 and transportation unit 440 may be temporarily or permanently coupled.

In various embodiments and with specific reference to FIG. 4A, control module 450 may communicate with multifunction unit 480 and instruct multifunction unit 480 to travel to a first location corresponding to a location of one or more cargo units 420. Upon arriving at the first location, multifunction unit 480 may be loaded or self-load cargo unit 420. Multifunction unit 480 may then be instructed via control module 450 to transport cargo unit to a second location such as near aircraft 410.

With reference to FIG. 4B, in various embodiments, multifunction unit 480 may be configured to lift cargo unit 420 to a cargo load door of aircraft 410. For example, control module 450 may communicate instructions to lift unit 430 of multifunction unit 480 and instruct lift unit 430 to lift cargo unit 420 or a sensor present on lift unit 430 may signal a need to lift cargo unit 420. In various embodiments, upon reaching suitable cargo elevation, transportation unit 440 may detach from lift unit 430 and transport cargo unit throughout a cargo bay of aircraft 410. Accordingly, in various embodiments, multifunction unit 480 comprising multiple subcomponents may be configured to transport cargo unit 420 from a first location to a second location autonomously.

With reference to FIG. 5, an exemplary sensing agent 500 is illustrated, in accordance with various embodiments. In various embodiments, one or more components of the autonomous end-to-end cargo handling systems described herein may comprise one or more sensing agents 500 in order to operate autonomously in addition to or instead of receiving instructions from a control module over a network. For example, in various embodiments, lift unit 330, transportation unit 340, and/or multifunction unit 480 may comprise sensing agent 500 in order to communicate with each other and/or monitor surroundings in order to transport a cargo unit from a first location to a second location (with momentary reference to FIG. 3A, FIG. 3B, FIG. 4A, and FIG. 4B). As such, lift unit 330, transportation unit 340, and/or multifunction unit 480 may create a distributed network of sensing agents 500 configured to locate, load, transfer, and/or move a cargo unit from a first location to a second location.

In various embodiments, each sensing agent 500 may comprise any suitable apparatus capable of monitoring and gathering data during the cargo loading process. Each sensing agent 500 may also be computer based, and may comprise a processor, a tangible non-transitory computer-readable memory, and/or a network interface, along with other suitable system software and hardware components. Instructions stored on the tangible non-transitory memory may allow each sensing agent 500 to perform various functions, as described herein.

System program instructions and/or processor instructions may be loaded onto a tangible, non-transitory, computer-readable medium (also referred to herein as a tangible, non-transitory, memory) having instructions stored thereon that, in response to execution by a controller, may cause the processor to perform various operations. The term “non-transitory” is to be understood to remove only propagating transitory signals per se from the claim scope and does not relinquish rights to all standard computer-readable media that are not only propagating transitory signals per se. Stated another way, the meaning of the term “non-transitory computer-readable medium” and “non-transitory computer-readable storage medium” should be construed to exclude only those types of transitory computer-readable media which were found in In re Nuijten to fall outside the scope of patentable subject matter under 35 U.S.C. § 101.

In various embodiments, each sensing agent 500 may also comprise various sub-components to aid in monitoring and gathering data. For example, each sensing agent 500 may comprise a sensing module 510 configured to sense a location of a cargo unit, a computing module 520, and/or a communication module 530. Sensing module 510, computing module 520, and/or communication module 530 may be in operative and/or electronic communication with each other. Computing module 520 may include logic configured to control sensing module 510 and/or communication module 530. In various embodiments, sensing module 510 may comprise any suitable apparatus, hardware, and/or software capable of monitoring a portion between two locations such as between an aircraft and a warehouse and/or freighter. Each sensing agent 500 may comprise one or more sensing modules 510. For example, sensing module 510 may comprise at least one of a camera, a structured light sensor, a light detection and ranging (LiDAR) sensor, an infrared sensor, a depth sensor (e.g., an IR projector/camera assembly such as a MICROSOFT® Kinect®, an ASUS® Xtion PRO®, etc.), a 3D scanner/camera, an ultrasound range finder, a radar sensor, and/or any other suitable sensing device. Each sensing module 510 may also comprise sensors to sense a weight of an object (a “weight sensor”) such as, for example, a pressure sensor, a piezo-electric sensor, and/or the like. Accordingly, lift unit 330, transportation unit 340, and/or multifunction unit 480 may be configured to adjust autonomously in real time to any variables not anticipated by the control module such as the presence of foreign objects between the first location and the second location, nonconforming cargo units, and/or adjustments to the first and/or second position. Further, lift unit 330, transportation unit 340, and/or multifunction unit 480 may communicate via communication module 530 of sensing agent 500 to transfer a cargo unit from a warehouse to transportation unit 340 and/or multifunction unit 480, from transportation unit 340 to lift unit 330, and/or from lift unit 330 and/or multifunction unit 480 to an aircraft.

As discussed herein, autonomous end-to-end cargo handling systems may be configured to efficiently and safely transport cargo units to and from an aircraft or other location without the need for human operators. Such systems may be reduce costs associated with human labor, reduce safety risks involved with human operators, and reduce human error associated with the scheduling and placement of such cargo units.
